Traffic Characteristics of Broadband Networks: Impact on Scalability

The networks as we see today are increasingly becoming more complex as additional nodes or computers are being added to it. It would be beyond expectations after few years as addition of latest mobiles would result in massive communication networks. This paper addressed most challengeable upcoming issue whether the present protocols would be able to function with the same efficiency in very large networks and so questions of scalability are observed. A protocol or network architecture is buffer scalable or scalable if the performance of the network with limited buffer space at each node does not degrade as the total size of the network increases. It is argued that mathematical treatment of large networks is essential as it is not feasible to build large networks for experimental purposes.
